Re: [flexcoders] Mostrar todas las filas de un DataGrid sin necesidad de scroll
Alex, you understood it very well hehe Let me answer him in Spanish...
Como dice Alex, puedes utilizar la propiedad rowCount para conseguir esto:
mx:DataGrid
id=myDG
dataProvider={ myAC }
rowCount={ myAC.length + 1 }
/
Observa que utilizamos rowCount vinculado a la longitud de nuestro
dataProvider + 1, suponiendo que tienes visibles las cabeceras del
datagrid. Puedes omitir este +1 si tienes las cabeceras ocultas.
Alex Harui escribió:
Not sure I understood this, but try setting rowCount to the length of
the dataProvider. You may also need to set verticalScrollPolicy=off.

Como puedo hacer para mostrar todas las filas de un DataGrid sin
necesidad de hacer scroll, ni de ninguna barra de desplazamiento.
Actualmente, y creo que por defecto, mi DataGrid muestra 6 filas, tenga
mas o menos información, sigue mostrando 6 filas, en caso de ser mas,
obviamente me agrega la barra de desplazamiento.
Lo que Yo quiero es que si hay 2 filas, muestre solo 2 filas y la altura
del DataGrid sea solo para mostrar las 2 filas, y si el DataGrid tiene
30 filas, muestre las 30 filas , por lo tanto el DataGrid tendra una
altura de 30 filas.
o sea
Altura del DataGrid = Cantidad Total de Filas
Muchas Gracias por todo

[flexcoders] Cast Exception from FDS to Hibernate
Hi all, I have an hibernate mapping defined with some properties and a relationship: set name=items table=... lazy=false key column=.../ one-to-many class=.../ /set This relationship is defined in the java bean as: private Collection items; On the Flex side, I'm receiving this relationship as an ArrayCollection. The serialization from java.util.Collection to Flex ArrayCollection works fine but, when I try to save the changes made on the client side ( what, on the server side, gets translated into getHibernateTemplate().update ( .. ) ), it just fails throwing this error: java.lang.ClassCastException : flex.messaging.io.ArrayCollection cannot be cast to java.util.Set Im stuck and I dont know what to do. Any ideas? Thank you! Alberto
[flexcoders] ValueCommit strange behaviour with comboBoxes
Hello all,
Whenever I try to change the selectedIndex in a comboBox, if the
selectedIndex is different from the current selectedIndex, it dispatches
2 valueCommit events instead of 1!! If I change it to the same index, it
just dispatches one! :o
Here's an example:
mx:Application
xmlns:mx=http://www.adobe.com/2006/mxml; layout=vertical
mx:Script
![CDATA[
import mx.collections.ArrayCollection;
[Bindable]
private var dp: ArrayCollection = new ArrayCollection( [
1,2,3,4 ] );
]]
/mx:Script
mx:Button label=change click=foo.selectedIndex = 3 /
mx:Button label=change2 click=foo.selectedIndex = 1 /
mx:ComboBox
id=foo
dataProvider={ dp }
prompt=Hello
valueCommit=trace( 'Event ' + event.type ) /
/mx:Application
Is this a bug??
Thank you in advance

Re: [flexcoders] Binding from Actionscript
Hi Ralf ! Im fine thank you! ( I will mail you personally at gmail )
Thanks for your help. I finally got that binding working! Paul sent me
some stuff (same stuff posted in flexcoders I think) and with some
time I managed to make it work.
In summary, I was creating the binding in the wrong place. I was
creating the binding in the class constructor and creating it in the
createChildren protected method made the trick, and the binding was
not a binding to a display object! :/ It was a binding from an object in
the model to a setter function in the class.
Anyway, thanks to everyone and specially thanks to Ralf and Paul in the
EMEA Adobe Consulting team.
Cheers,

[flexcoders] Image source path bug?
Hi all, Im experiencing an strange behaviour (bug?) with the Image tag in Flex2b2. If I use the tag like: mx:Image source=foo.jpg / it works when compiled with Flex Builder and the image displays correctly. If I move this application (and picture) to j2ee server, I type the url in the browser and the application runs but no image is displayed. A simple application like this : [testImage.mxml] mx:Application xmlns:mx=http://www.adobe.com/2006/mxml; xmlns=* mx:Image source=transportes.jpg / /mx:Application does not show any image (only a broken image icon) when accessed through : http://./testImage.mxml But, If I run this sample using Flex Builder it works fine. And if I run locally (not through a browser) the generated swf at the j2ee server it works fine. And accessing that same swf through the web browser, it does show that broken-image icon! Is this a bug? Thanks in advance -- Alberto Albericio Salvador Aura S.A.

[flexcoders] How to extend a radiobutton component?
Hi all,
I want to extend the RadioButton component so that it becomes something
like:
the radiobutton itself + something else (vbox, canvas, ...)
How can I do this? Right now, Im trying this:
mx:RadioButton xmlns:mx=http://www.macromedia.com/2005/mxml; xmlns=*
selected={mySelected}
mx:Script
![CDATA[
[Bindable]
public var myData:Object;
[Bindable]
public var mySelected:Boolean;
]]
/mx:Script
mx:HBox
mx:Label text={myData.name} /
mx:Canvas visible={mySelected}
mx:Label text=Secondary info /
/mx:Canvas
/mx:HBox
/mx:RadioButton
The Script code works, it is extending the component fine but the visual
addon is not working, I mean that HBox.
It is important for me to extend the radiobutton component and not
create a new VBox with a radiobutton on it because im creating these
components from a Repeater and it should behave as a RadioButton.
Any ideas?
Thank you all.
Albert

Re: [flexcoders] Dynamic UI question

the repeated objects instead of resizing the item at the TileList and
show the full component.
In approach 2, the Tile item resizes fine only If I select the checkbox
at the first position. If I press the checkbox at the second, It resizes
the second item and also resizes the first one!
Basically, Im driven myself mad trying to make this working. Has anyone
a working example on something similar? A vertical repeatr component
with expandable items? or what am I doing wrong?

I've encountered this annoying bug today.
When using the formatFunction attribute of DateField, when the component
looses its focus, it erases the date text field.
To reproduce the problem, simply execute the following code from LiveDocs,
select a date and move the focus to the other text input:
mx:DateFormatter id=dfconv formatString=/MM/DD/

There is a simple workaround, but it does not work all the time:

Re: [flexcoders] Dispatching events from cairngorm viewhelper
Hi Alex,
I stopped playing with ViewHelpers in the 80% of the cases. I was
overloading the use of ViewHelpers and thank God I soon realized of
that. To make more reusable components, I prefer embeding script code
into the mxml file, use reusable commands (this was discussed in another
thread) and dispatch events from the same component.
Talking about the other 20% of cases, I use your (and some other guys)
approach of dispatching events from the parent view or the main
application that both extend display objects.
Thanks again for your help and please read my new post about Cairngorm
and memory Im just writing in a sec hehe

Alex Uhlmann escribió:
Hi Alberto,
When dispatching events you have to be sure that the object you call
dispatchEvent from is a display object (all display objects extend
flash.events.EventDispatcher) and is on the display list. i.e. as Dirk
mentioned you can call the dispatchEvent method in your MXML file because it
is on the display list and extends EventDispatcher. If you want to trigger a
Cairngorm Command with your call you could access the most parent display
object your application in mx.core.Application.application. So,
Application.application.dispatchEvent(event);. From your View Helper, I would
just access the view of your MXML file to dispatch an event. Flex then uses
event bubbling and triggers the registered Command.
Best,
Alex

[flexcoders] Cairngorm and memory administration
Hi all, When using Cairngorm (usually for middle-large developments), lots of events, services, commands, etc start to move behind the scenes: new Delegates, new Events, etc... so my question is, when are these objects removed from memory? Imagine I have a screen that loads products depending on some options. Each time these options change, I must recall the products load that means:dispatching new event with new options (new event), passing control to the command, then to the bussiness delegate (new delegate), etc... So, if I want to display products depending on 10 variations of these options, I must use the same mechanism to get the new product list... thats 10 new delegates, events, etc on memory? What if I set to Nothing the new Delegate created after each use? -- Alberto Albericio Salvador Aura S.A.

[flexcoders] Binding question
Hi all,
I dont know why, but the Flex compiler alerts some error when I try to
use binding with 2 arguments:
mx:VBox visible={someCombo.selectedIndex != 0
someOtherCombo.selectedIndex != 0}
...
/mx:VBox
And the error is : The entity name must immediately follow the '' in
the entity reference
Using a function, it works fine
mx:VBox visible={isThisVisible()}
...
/mx:VBox
where:
private function isThisVisible():Boolean {
if (someCombo.selectedIndex != 0 someOtherCombo.selectedIndex !=
0) return true;
else return false;
}
Why and how to solve this so I dont have to fill my code with these
functions?

Hi all,
In Cairngorm commands, I always define statically where I want some
results to be sent (normally a custom function in component that
extends ViewHelper). This updates my view and works fine. But...
How can I make that command Class to send some results to whatever
asked for them (who dispatched the event that threw that command)?
Eg:
foobar1.mxml and foobar2.mxml
..
public function setResults(someResults):void {
//update my controls
}
public function getResults():void {
dispatchEvent(askForResults);
}
foobar1 and foobar2 dispatch the same event and the command needs to
know where to send back the results and run setResults on the
corresponding caller. How can I achieve this?
Thanks in advance

Re: [flexcoders] Cairngorm2 reusable commands
Hi Joao,
I dont agree at all hehe For me, it is ok that commands know about views
(or whatever dispatches the event that started that command)
Imagine this situation:
You have a screen where 2 components ask for the weather on a zip code,
so I can see weather on 2 locations at the same time. What I say is:
I need both components to dispatch the same event(getWeather) but with
different parameter (zip code) and get the results back to them using
the same command. I dont want to use a single application pool to store
my results.

Alberto,
In my opinion commands shouldn't be aware of the views. It's not what
cairngorm is made for. Dispatch your event and set the result to some
variable in your ModelLocator. Then if foobar1 and foobar2 need that info,
use bindings and bind them to that variable ... Do you need to transform that
information in a different way for each one? Fine, use the Foobar1ViewHelper
and Foobar2ViewHelper to do it.
Example:
Foobar1.mxml
mx:Script
![CDATA[
Import your.model.locator.path.ModelLocator;
[Bindable]
public var model:ModelLocator =
ModelLocator.getInstance();
]]
/mx:Script
mx:Combobox dataProvider={Foobar1ViewHelper.formatMyModel(model.myVar)}/
Foobar2.mxml
mx:Combobox
dataProvider={Foobar2ViewHelper.formatDifferentlyMyModel(model.myVar)}/

Using the ArrayCollection instead of Array, that do not update controls

Re: [flexcoders] Binding refresh
Hi Jonathan,
If your're working with Flex2, try using an ArrayCollection instead of
an Array. The Array class does not throw any event on change to update
such controls anymore.

Firing the event from a function of the main view, same code, it works fine.
My function is something like, same in the view and in my custom viewhelper.

I have chosen your second approach and it works fine: thats letting my
view to dispatch the event.
Thank you very much

To dispatch events, your ViewHelper class has to extend

the event for you, i.e. inside your ViewHelper something like
view.dispatchEvent(theEvent);

Re: [flexcoders] Dispatching events from cairngorm viewhelper
Joao,
Im using cairngorm 2a2 and my event extends CairngormEvent but the
problem is not with the event but with dispatchEvent method:
Im meaning, in this function, LocalidadesEvent extends CairngormEvent
public function getPoblaciones(cp:String):void {
var event : LocalidadesEvent = new LocalidadesEvent(cp);
dispatchEvent(event);
}
But I get the error:
Call to a possibly undefined method 'dispatchEvent'
Im using the same code in the main view and in the helper and it should
work, but it doesnt.

OK if you are using cairngorm 2alpha2 you should be able to use it like this
In your viewhelper you should import the new cairngormEvent

And your event should extend cairngormEvent
It should work,

[flexcoders] Flex2 combobox performance
Hello all, I've noticed that performance of mx:ComboBox is really low. I mean, when using a Flex2b1 combobox component, expanding its contents gets lagged, not fluid.

[flexcoders] Automatic layout positioning
Hi all, When defining non-basic form layouts, I need sometimes to hide/reveal extra information or editable areas. When doing this, I need the rest of the form to automatically rearrange, similar to setting the document.getElementById(foobar).style.display = none or = in HTML. If I try to use the visible property in Flex, it just hides/shows the UIcomponent but it does not rearrange anything. Is there any trick or official procedure to emulate this behaviour?

[flexcoders] Cairngorm ViewHelpers
Hi,
When using Cairngorm 2.0a2, how can I make use of the ViewHelpers?
Trying to attach a viewhelper to the login example, I write this class:
// loginViewHelper.as
package org.nevis.cairngorm.samples.login.view {
import org.nevis.cairngorm.view.ViewHelper;
import mx.controls.Alert;
public class loginViewHelper extends ViewHelper
{
public function loginViewHelper() : void
{
}
public function sayPo() : void
{
mx.controls.Alert.show('Popopopopopop');
}
}
}
What am I doing wrong here that the compiler is arguing about Cairngorm
ViewHelper.as and Cairngorm ViewLocator.as?
Thanks

[flexcoders] Binding question
Hi all,
When I bind a text label to the first position of an array like this :
mx:Label text={ ModelLocator.SOMEARRAY[0] } /
The text shows the first item of the array correctly.
When I add a new item to the array, the text of the label does not
change so it seems the binding is not really working.
I know Im adding items to the array correctly because I have a list
bound to ModelLocator.SOMEARRAY and it's working fine.
What am I doing wrong?
Thanks in advance

I forgot to mention Im adding items at the beginning of the array, at

Re: [flexcoders] Binding question
Indeed... I thought this was basic binding so I didnt look at any
documentation... I more thought it was a bug :)
Thanks anyway for the answer Abdul
Abdul Qabiz escribió:
Hi,
If you look at this link of Flex Documentation:
http://livedocs.macromedia.com/flex/15/flex_docs_en/0695.htm
You will find the following in the end:
Note: Array elements do not trigger ChangeEvents and, therefore, cannot
function as binding sources at runtime. Binding copies initial values during
instantiation after variables are declared in an mx:Script tag, but before
handlers are executed. Arrays that are bound do not stay updated if individual
fields of a source Array change.
I don't remember the exact workaround of this problem, please check the
flexcoders archive I am sure this has been dicussed many times. Also check the
FAQ, I think it might be there also.

[flexcoders] Strange List behaviour
Hi all, Im using a List component to display the messages incoming from a msg push server. The dataProvider of the List is bound to some array variable. If I use the method *addItem* to inject data into the array; as a result of this action, the List grows downwards, leaving the first element always visible and loosing the last added msgs lost (gotta use the scrollbar to find them at the end). Well, I want the List to grow upwards so that the last incoming msg gets displayed the first. I use the *unshift* method but the array does not get modified. So, what is happening here? I know this is not a natural Flex question but I cant find why it is not working the way I want.

[flexcoders] Cairngorm question
Hi all, The Cairngorm samples are a great resource for understanding how to best arquitect an specific kind of applications; in this case, applications that talk syncly with some servers that expose some services. Imagine now that Im building an application which implements, somewhere, some kind of asynchronous services: a flash comm server chat , for example. This service must be running, in the background, even if im visually working in another part of the application, entering some data for new providers or whatever. So the question is, where is the best place to initialise these services? Or how can I place/work with these services within this arquitecture? My choice would probably be to initialise evrything inside a initialise() function in the model locator and then use some public var there to control msgs and status of this service and then bind the chat components to these vars. I hope someone can help chosing the best option. Thanks all in advance. -- Alberto Albericio Salvador Aura S.A. Seguros Departamento Informática Yahoo! Groups Sponsor ~-- Get Bzzzy!

Re: [flexcoders] Re: Cairngorm question
Hi Alex, I like the idea of Listeners and they way you point to manage server pushes injecting events and data to the Cairngorm architecture. Mainly because server pushes are treat just like if they were data from a user-gesture. If possible, send me a sample code for one of these Listeners, just a short one so I can see how to initialise the subscription and how handlers for server pushes are defined. I can imagine it's somehow similar to a business delegate class calling a remoteobject but I dont see how to leave these services in the background listening and waiting for server pushes. Thanks for your help Alex. Alex Uhlmann escribió: Hi Alberto, in addition to what Dan said, you could create an object similar to Business Delegates used for request/response remote calls - in applications that we have developed, we call these Listeners. These listeners provide control and protection for your server push remote services. In here, you could implement functionality as recovery plans, disconnecting etc. In these listeners, we would typically subscribe to server-side shared objects. When we receive notification of changes to the shared object, we then convert untyped FlashComm data into VOs, before using the EventBroadcaster in our listener to broadcast events plus data. So the listener is really just another way of injecting an event into the Cairngorm architecture, other than a user-gesture. In this way, the commands are unaware as to whether the events that called them, and the data accompanying these events, was pushed from the server (via FlashComm) or generated on the client. Everything else about your Cairngorm architecture remains the same - using the ModelLocator for instance, to have your commands updating the model, and binding the view to the state of your model. Depending on the complexity of your application, we might suggest further refactorings, i.e. outsourcing functionality of listeners to other classes such as recovery plans.

Re: [flexcoders] Re: Cairngorm question
Hi again,
Im trying to create a business delegate class for handling a connection
to, for example, an xml socket.
When trying to delegate onXML to the responder it keeps on saying there
is not such property on the responder, but of course there is. If I
define the function inside de business delegate class, it works
(changing responder.myOnXML for myOnXML, of course)
I have something like this on my command class:
class org.nevis.cairngorm.prexon.commands.SubscribeCommand implements
Command, Responder {
public function execute( event:Event ) : Void {
var delegate: SubscriberDelegate = new SubscriberDelegate( this );
delegate.subscribe( );
}
public function myOnXML( event : Object ): Void {
mx.core.Application.alert(RESPONDER OK);
}
..
}
And the business delegate has:
this.responder = responder; (the parameter for the class)
myListener.onXML = Delegate.create( responder, responder.myOnXML );
...
What Im I doing wrong? Is it okay setting a responder here? Cause I have
to define a result and fault handler im never using for this kind of
services...

Alberto,
this seems a fair approach to me, you may also want to include some
logic to disconnect from the flash comm server when you know you are
not interested in receiving updates and maybe even a 'recovery plan'
for the service should the connection to the FCS be broken.

[flexcoders] XMLsocket behaviour

In my Flex application, I use XMLsocket to receive some server msgs.
onConnect, onClose, etc events work fine but, when I cant connect to the
socket, how can I tell mySocket to try reconnecting every, lets say, 20
seconds?
I want something like : .onNotConnected = function () { ... } every 20
seconds :)

Alberto,
The onConnect callback receives a Boolean flag True if connected and False
if not connected. When false just reconnect.
function onConnect(connected){
if (connected){
//connected
}else{
Sock.connect( Sock.server , Sock.port )
}
}
Although, when connected is false it return with a slight delay, so you
might just connect there.

[flexcoders] Flex, Remoting and more
Hi all, I've been reading about connecting flex client applications using Flash Communication Server(FCS) and shared objects. Thats seems to cover the needs for developing chat-like applications... Now, imagine I have an external Notification server (yukon notification server, or whatever) And I want FCS to listen *persistently* to this server. With FCS and Remoting I know how to POLL a database 1 time or every 10 seconds and format that answer to feed the FCS but HOW can I create a persistent link to a notification server,socket server or similar, get the data this server is pushing, format this data and pass it to the FCS? So basically, I want to know how to replace POLLING with PERSISTENT LISTENING. Example application: A Flex application that shows the queue of a call center. When a new call arrives, it is shown in every client running the application. And it is the call center notification server that tells the FCS it has received the new call and NOT the FCS that polls the queue of the notification server to see if there is any new call pending.
